Examples of org.apache.oozie.service.HadoopAccessorService

org.apache.oozie.service.HadoopAccessorService
The HadoopAccessorService returns HadoopAccessor instances configured to work on behalf of a user-group.
The default accessor used is the base accessor which just injects the UGI into the configuration instance used to create/obtain JobClient and ileSystem instances.
The HadoopAccess class to use can be configured in the oozie-site.xml using the oozie.service.HadoopAccessorService.accessor.class property.

        Path configDefault = null;
        try {
            String bundleAppPathStr = conf.get(OozieClient.BUNDLE_APP_PATH);
            Path bundleAppPath = new Path(bundleAppPathStr);
            String user = ParamChecker.notEmpty(conf.get(OozieClient.USER_NAME), OozieClient.USER_NAME);
            HadoopAccessorService has = Services.get().get(HadoopAccessorService.class);
            Configuration fsConf = has.createJobConf(bundleAppPath.toUri().getAuthority());
            FileSystem fs = has.createFileSystem(user, bundleAppPath.toUri(), fsConf);


            // app path could be a directory
